METHOD FOR TEMPERATURE DETERMINATION OF CONDENSED PHASE PARTICLES OF MOVING HETEROGENEOUS OBJECTS Russian patent published in 1998 - IPC

FIELD: determination of temperature of moving objects-particles. SUBSTANCE: radiation intensity is measured at decomposition into spectrum. Spectral intensities are summed up during measurement on N wave lengths from flying unequally heated particles of condensed phase observed when heterogeneous object moves in lateral direction relative to preset section. Then total thermal spectrum U is obtained from unequally heated particles. This spectrum is vector of the following values: u(l₁), u(l₂)...u(l_i)...u(l_N), where u(l_i) is total spectral intensity obtained on wave length l_i. This done, histogram Z of temperature distribution of particles is determined. It represents vector of values Z(T₁), Z(T₂),...Z(T_N) at N preset temperature in compliance with the following formula: Z = A^-1•U (1), where A is size N.N matrix of values {a(l_i, T_j)} of spectral intensity of black body radiation determined by Planck radiation formula on each of measured N wave lengths and at each of N preset temperatures. Average temperature of particles is found from formula . EFFECT: higher measurement results. 1 dwg
